JOSEPH HORLIN-- ROBINSON AND LILLARD FILSON ROBINSON, OF ADAMS,TENNESSEE.

Application filed September 7, 1911.

Specification of Letters Patent.

Patented Mar. 5, 1912.

Serial No. 648,026.

To all whom it may concern:

Be it known that we, JOSEPH H. ROBINSON and LILLARD F. ROBINSON,citizens of the United States, residing at Adams, in the county ofRobertson and State of Tennessee, have invented certain new and usefulImprovements in Combined Planters and Fertilizer-Distributers, of whichthe following is a specification, reference being had to theaccompanying drawings.

This invention relates to improvements in combined planters andfertilizer distributers and has for its object to provide a machine ofcomparatively simple construction whereby the corn or other seed beingplanted may be dropped in hills and the hills suitably marked orchecked.

A further object of the invention is to provide means for facilitatingthe turning of the machine at the end of a row.

Still another object resides in the provision of novel means fordropping the seed and fertilizer at predetermined intervals into thedepositing chutes.

Still another object of the invention is to provide a rear supportingroller arranged between the main supporting wheels of the, machine andadapted to support the machine.

when the same is being turned, and means for raising and lowering saidroller.

With the above and other objects in view, the invention consists of thenovel features of construction, combination and arrangement of partshereinafter fully described and claimed, and illustrated in theaccompanying drawings, in which- Figure 1 is a side elevation of acombined planter and fertilizer distributer embodying our improvements;Fig. 2 is a top plan view;

Fig. 3 is a longitudinal section taken on the line 3-3 of Fig. 2; Fig. 4is a transverse section taken on the line 4-4 of Fig. 2; and Fig. 5 is adetail sect-ion taken on the line 55 of Fig. 2.

Referring in detail to the drawings 5 designates the main frame of themachine which is mounted at its rear end upon the axle 6. Upon the endsof this axle the supporting wheels 7 are revolubly mounted. The frame 5extends forwardly of the supporting wheels and upon the same the seedand fertilizer boxes 8 are arranged. These boxes are disposed atopposite sides of the machine and in line with the supporting wheels.

Each of the boxes 8 is divided by a central I partition 9 into twoseparate compartments 10. The forward compartments are adapted tocontain the corn or other seed to be planted while in the rearcompartments a suitable fertilizing material is contained. The slidableseed dropping plates 11 are arranged between the boxes 8 and the frameupon which they are mounted, said plates being provided with theopenings 12 to register with openings 13 in the bottom of the seed andfertilizer compartments. Directly beneath these compartments the chutes14 and 15 are arranged, the chute 14 receiving the fertilizer and beingsecured at its lower'end to the ground opening shoes 16. The upper endof the chute 14 is hingedly secured to the frame as indicated at 14. Theother chute 15 which receives the seed is disposed at an angle andcommunicates at its lower end with the chute 14. At this point the seedand the fertilizer are mixed and are then deposited in the furrow openedby the shoe. The seed dropping plates 11 are adapted to be reciprocatedbeneath the boxes and are actuated in the following manner. In the frame5 immediately in the rear of the boxes 8, a transverse shaft 17 ismounted to oscillate. Upon this shaft the arms 18 are rigidly fixed andlinks '19 connect said arms at their free ends to the lugs 20 on theends of the plates 11. One end of the shaft 17 is extended beyond theside of the frame and has secured thereto a block 21. A finger 22 ispivoted upon this block and is adapted to be engaged by a series of pins23 projecting from the outer face of one of the supporting wheels 7.This finger has pivotal movement in only one direction, and isyieldingly held against such movement by means of the leaf spring 24. Itwill thus be seen that in the backward movement of the machine, theengagement of the pins 23 with the finger will not oscillate the shaft17. In the forward movementof the machine, how ever, the pins strikesaid finger and force the block 21 downwardly thereby oscillating orrocking the shaft 17. This oscillation of the shaft moves the seeddropping plates rearwardly through the medium of the connections abovedescribed until the openings in said plates register with the openingsin the bottom of the seed and fertilizer compartments so that the seedand fertilizer is dropped into the rear end of the shoes 16. To theshaft 17 an arm 25 is secured to which one end of a rod 26 is connected,the

v other end of said rod being loosely disposed in a suitable support 27arranged upon the machine frame. A coiled spring 28 is arranged on saidrod and is secured at its ends to the arm and the support. It will thusbe seen that when the shaft is rocked this spring is placed undertension and when the pin on the Wheel is disengaged from the finger 22,said spring immediately returns the shaft 17 to'i ts normal position andforces the seed dropping plates 11 forwardly thereby cutting off thefeed of the seed and fertilizer.

In order to insure the proper feed of the fertilizer and prevent thesame from sticking to the walls of the compartments 10, we provide thetransversely disposed shaft 29 which is mounted in the walls of saidboxes and is provided at its ends with the agitating fingers 30 whichengage the fertilizer and break up the same so that it will flow freelythrough the openings in the bottom of the compartments. This shaft isrotated through the medium of a link 31 which connects the arm 32 fixedto the shaft 17 with a crank arm 33 on the shaft 29. Thus the agitatoris actuated simultaneously with the sliding movement of the seeddropping plate so that the proper feed of the material is positivelyassured.

In order to facilitate the turning movement of the machine at the end ofa row, we provide the roller 34 which is arranged between the supportingwheels 7 and rearwardly of the axle 6. This roller is rotatably mountedin a frame 35 which is journaled intermediate of its ends upon supportsarranged beneath the wheel axle 6. A lever 37 carries the usual springactuated dog for engagement with the teeth of a rack 38 to hold saidlever in its adjusted position, and this lever is connected by means ofa link 39 to the cross bar 40 in the forward end of the frame 35. Itwill thus be seen that by manipulating the lever 37, the cross bar 40 israised or lowered and the frame 35 oscillated upon its fulcrum to raiseand lower the supporting roller 34. Upon the frame 5 a second lever 43is mounted together with its rack 44 and is connected by means of a link45 to an upright arm 46 fixed to the transverse shaft 36 mounted uponthe main frame 5. A bar 46' is longitudinally disposed beneath theplatform upon which the seed and fertilizer boxes are mounted and ispivoted intermediate of its ends upon a rod 49 fixed in the frame foroscillatory movement. A rod 50 connects the rear end of this bar to astud 36 which is fixed to the transverse shaft 36. A rod 51 connects thefurrow opening shoes 16 and extends through the forward end of thelongitudinally disposed bar 46. The spouts 14 are hingedly secured attheir upper ends to the under side of the frame 5 which is provided withsuitable openings to receive the fertilizer. By adjusting the lever 43,the furrow opening shoes may be elevated out of contact with the ground.By means of this arrangement of parts, it Will be readily seen that themachine may be easily and quickly turned upon arriving at the end of arow by lowering the roller 34 until the supporting wheels 7 are liftedout of contact with the ground. The shoes 16 are then elevated and owingto the fact that the roller 34 is centrally disposed, and has Verylittle ground engaging surface, the resistance offered to the turningmovement of the machine is comparatively small. After the machine hasbeen turned, the roller is elevated and the shoes lowered to theiroperative positions.

A suitable marker 47 is arranged upon an arm extending laterally fromthe rear end of the machine and provides a suitable guide line so thatthe seed hills may be deposited in parallel rows.

The rims or treads of the ground wheels 7 are of concave-convex form incross section and form the ridge or hill over the seed as it is dropped.This wheel rim is provided with a plurality of openings 52 and thedistance between adjacent openings is equivalent to the dist-ancebetween the said hills so that each hill is plainly marked by a smallmound or hillock of earth which enters these openings. In this mannerthe hills are properly checked.

From the foregoing it is thought that the construction and operation ofour improved machine will be readily understood. There are comparativelyfew elements employed in the construction so that the machine as a wholewill be extremely durable and require only small and infrequent repairs.It will of course be understood that the machine is as well adapted forplanting seed in drills and either with or without the fertilizer. Whilethe machine is primarily designed for the planting of corn, it will beunderstood that the invention is not restricted to such use as it mayalso be employed for the planting of other grain seed, tobacco andsimilar agricultural products. The machine is also susceptible ofconsiderable modification in the form and construction of the variouselements without departing from the essential feature or sacrificinganyof the advantages thereof.

Having thus described the invention what is claimed is 1. Thecombination with a wheel supported frame, of seed and fertilizer hoppersrigidly mounted upon opposite ends of said frame, seed and fertilizerreceiving spouts arranged beneath the frame, the seed receiving spoutbeing hingedly secured at its upper end to said frame, and means mountedupon said frame to swing said depositing spouts to an inoperativeposition beneath the hoppers.

2. The combination with a wheel supported frame, of combined seed andfertilizer hoppers rigidly mounted upon said frame, seed receivingspouts hingedly secured at their upper ends to the frame, fertilizerreceiving spouts carried by the seed receiving spouts and communicatingwith the same adjacent their lower ends, furrow opening shoes rigidlyfixed to the seed receiving spouts at their lower ends, a cross barconnecting said shoes, and operating Copies of this patent may beobtained for means mounted upon the frame and connected to said crossbar whereby said seed and fertilizer receiving spouts and the shoes maybe swung beneath the frame to their operative or inoperative positions.

In testimony whereof we hereunto affix our signatures in the presence oftwo witnesses.
